Conservation of Linear Momentum
... Given that considerations of equation (3.10) led us to the principle of conservation of energy in Chapter 2, and that equation (3.11) for the momentum and impulse has a form that is basically similar to that of equation (3.10), it is then reasonable to expect that we would also have conservation of ...
